-LRB- CNN -RRB- -- Reality TV star Tila Tequila suffered facial cuts when she was pelted with rocks and bottles while performing at a music festival in Illinois early Saturday , according to a witness and a law enforcement official .

`` She 's pretty cut up , '' said a performer who saw the violence at the `` Gathering of the Juggalos '' in rural Hardin County , Illinois . The witness asked not to be identified so that he does not anger the juggalos .

Tequila , a Playboy model who also sings , posted a Twitter message Saturday , saying she would sue the festival , which is organized for fans of the hip-hop group Insane Clown Posse .

`` Pretty soon , the owners who run the juggalos will be bankrupt , '' she tweeted .

The fans are mostly young people who sometimes wear clown make up and are referred to as juggalos and juggalettes .

Festival organizers did not immediately respond to CNN requests for a response .

The performer said a mob of hundreds chased Tequila from the stage and surrounded the trailer where she sought refuge . They rocked the trailer and smashed its windows , the witness said .

Tequila eventually escaped , but only after windows in her SUV were smashed , he said .

Hardin County Sheriff Tom Seiner , who offered a similar description of the events , said he has an open investigation . It would be `` very hard '' to identify the attackers unless he can locate video of the incident , the sheriff said .

Tequila offered her descriptions of the events in a statement to celebrity news website TMZ .

`` I went onstage and immediately , before I even got on stage , dudes were throwing huge stone rocks in my face , beer bottles that slit my eye open , almost burnt my hair ... cuz they threw fire crackers on stage , '' she wrote .

The witness , who was standing in the rear of the stage , said the crowd of about 2,000 was immediately angry toward Tequila and she was unable to turn them around .

`` She was taunting them , '' he said . `` She did n't know how to handle them . She did n't understand the dynamic . ''

The rocks and bottles flew harder and faster when Tequila bared her breasts , he said .

`` She took her top off and they got really violent , '' he said .

Tequila continued to perform even after her face started bleeding , he said . `` She was holding a towel to her head , blood pouring down her face , '' he said .

`` It was scary as hell ! '' Tequila wrote .

This was not the only violent incident at the festival early Saturday , Seiner said .

A 49-year-old Georgia man was arrested for allegedly stabbing another man in the abdomen just hours earlier , he said .
